FLUSH|-NG APPARATUS FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 378,100, dated February21, 1868.

' Application filed January 25, 1886. Serial No. 189,581; (No model.)

To aZZ whom it may concern: Be it known that I, SAMUEL G. MOFARLAND, ofthe city and State of New York, have invented an Improvement in FlushingAppara-.

tus for Water-Closets, of which the following isa specification.

The object of this invention is to create a suction between the twotraps of the watercloset sufficient to produce a siphoning action thatdischarges the con-tents of the closet-basin.

To effect this object the entire flushing-cistern is inclosed, so thatthe descent of the water therein when it fiows to the closet-basin proThe flushing-cistern A is of any desired size,

or shape, and the water is to be supplied into the same by a ball-valveor other convenient mechanism. B is the pipe leading from theflushing-cistern to the rim G of the water-closet bowl D, and within theflushing-cistern A is a siphon-pipe, E, with a valve, F, at its lowerend, and this pipe and valve are lifted by a 10d,G, and any suitableconnection to the pull passes. 'rod G; but ordinarilyit is sufficient tomake of the water-closet. The parts thus far named are of any ordinarycharacter, exceptthat the flushing-cistern is closed on the top by aplate or plates, H, that is air-tight,or nearly so, and in the same is ahole through which the rod G There may be a packing around this the holebut slightly larger than the rod.

At the back of the watencloset bowl D is the vertical dam T, and asiphon-discharge, K, leading down to the lower trap, L, that intervenesbetween the siphon and the sewer-pipe M,and the partition P,between thesiphon and the bowl D, is convex at the side next the bowl D, asshown inthe drawing, the object of this convexity being to throw the water thatissues from the flushing-rim O at the back of the closetsufficientlyaway from the dischargeopening between the basin and the siphon to fallupon andsubmerge any paper that may bepartially floating in the water ofthe basin,and thereby compel the discharge of the paper with the rest ofthe contents of the basin through the siphon and trap, as hereinafterstated.

From the upper part of the siphon K a pipe, S, passes up into theflushing-cistern, the upper end being near the under side of the coverH.-

- flushing-cistern rushes rapidly down the pipe B into the bowl of thecloset through the flushingrim 0, and the wateroverflows thevertical damT in the siphon K, and the descent of the water in the cistern Aproduces minus pressure of atmosphere in the upper part of said cisternand'draws the air out of the siphon K through the pipe S, so that thissiphon fills with water, and the column of water in said siphon K, thetrap L, and sewer-pipe M causes a powerful current that draws the waterout of the bowl D and discharges the contents thereof, andauy paperwhich might otherwise float iuthe-bowl is submerged and carried awaywith the water, as aforesaid. The rapidity of discharge causes the levelof the water in the bowl Dto'descend so rapidly that air is drawn intothe siphon K and the same ceases to act, and air rushes up into thecistern to supply the minus pressure therein. The water runs fromthecock Q to refill the cistern,and I providea smallpipe,R, opening atits lower end below the valve-seat into the pipe B, and the upper end isin the discharge-opening of the cock, so that a porobstructed.

I do not claim a water-closet cistern in which there isa-flushing-chamber closed at the top and provided with an air-valve andwith a valve to admit water into the flushing'chamher, and aflushing-pipe and valve leading to the closet, and an air-pipe from thetrap of the closet up into the-flushing-chamber; neither do I claim acloset-basin having inclined concavo-convex sides over which the waterflows and in which the action of the water is nearly uniform all aroundthe basin. By my improvement the water acts above the trap to submergepaper or other floating substances, and at all other portions of thebasin to drive the contents of thebasin toward the discharge-openin g.

B, leading to the rim of the closet, a. valve at 15 the upper end ofsuch pipe, a siphon-tube connected with thevalve, and a rod passingthrough the cover of the cistern and connected to the siphon and valvefor lifting the same when the closet-pull is operated, substantially asset 20 forth.

Signed by me this 2lst day of January, A. D. 1886.
